COFFEE A ND PEANUT ROASTER.

SPECIFICATION forming part of Letters Patent No. 256,428, dated April11, 1882.

Application med september 13,1881. (Model.)

' Be it known that I, CHARLES L. COLE, acitizen of the United States,residing at Bushnell, in the. county of McDonough and State of Illinois;have invented certain new and useful Improvements in Coffee and PeanutRoasters; and I do hereby declare the following to bea full, clear, andexact description of the invention, such as. will enable others skilledin the art to which it appertains-to make and use the same, referencebeing had to the accompanying drawings, and to letters or figures ofreference marked thereon, which form a part of this specification.

Figure 1 is a perspective of the entire device. Fig. 2 is averticalcentral section ofthe device as shown in Fig. l. Fig. 3 is acrosssection of that part of the device which contains the furnace androaster. Fig. 4 is a detail of one of the strips inside the cylinder.Fig. 5 is a detail, showin'g the exitiue.

This invention belongs to that'class of devices known as coffee orpeanut roasters; and Vthe distinguishing features or points of novelty ilarly be set out and explained.

In the accompanying drawings, A denotes that part of the device whichcontains the t'urnace B and the roasting-cylinder C. This part ispreferably of the shape ot' a parallelogram in horizontal cross-section,but is considerablyv higher than it is broad. The furnace 0r heatfing-chamber B is constructed and 'finished in any desired way to insurethe greatest amount of heat in the chamber about the roasting-cylinder,which is placed centrally lengthwise in the part A and above thefurnace. Thiscylinder is made of sheet metal, and, while called volved,its ends being left open, itscontents.

will be discharged vinto said hopper'and then 5o tlow down through thevspout cinto any convenient receptacle. Around the under side of saidcylinder is the semi-jacket F. This extends from end to end ofthe casingA, but is. of less diameter, and thus is allowed'a free space at eachside ot' the cylinder C for the 55 upward flow of the heat and volatileproducts Ot' combustion from the furnace. This cylinder is hungon andrevolved by means of shaft D, which is mounted in the strap d,projecting from one end of the casing A and in the wall 6o 0f thedischarge-hopper at the other end. The

flanged heads c, at the ends of the cylinder, are outside ofthe endWalls of the structure A'. Across the middle of the cylinderandnear eachend are the strips'c. centrally through them. In the head opposite thecrank are hinged the semicircular doors c, which open outwardly, and are.properly v supplied with latches, so that they maybe opened or closed,as desired, to put intoor re- 7o move peanuts, coffee, &c.,'from thecylinder. These doors may also have sliding doors, it' desired. In theopposite head ot' the cylinder C is xcdcentrally the cone C. -In thehead around the. edges of the coneare slots or open- 7 5 ings c3.

The annular door c, around the cone', is adapted to cover these. Thecrank D passes through the apex of the cone. Coffee or. peanuts may befed into the cylinder C through the opening c5`in said co'ne while saidcylinder 8o is in motion, so that its revolution need not be stopped forthe purpose of supplying thema-V terial to be roasted. This openingshould be provided with a suitable cover. By opening,

the annular door c1 the cylinder may be emp- 8 5 tied without stoppingits revolution.

When at rest the cylinder C may be filled through the pipe G, whichextends down from the dished shaped receptacle a in the top oftheStructure A. By pulling outward the valve H a, extends entirely acrossthe top of the chaml ber of combustion beneath the receptacle a.

The walls of' the structure A, in the space beroo v The axle D passes-65 The pipe Gr has will escape through the exit-pipe I. A damper, i,suitably controls this exit.

It' desired to throw some heat under the warmin g chamber or receptacleK, the damper i', which controls the passageway b between thefurnace-chamber B and space L in the center horizontally of thestructure K, may be opened. The volatile products ot combustion willescape t'rom this chamber through the pipe I', which extends from theupper front end of the heating-chamber under the exhibitor K andconnects with the exit-pipe I.

The provision of the jacket or shield F beneath and extending somethin gmore than onehalf around the cylinder C will prevent volatile productsof combustion from escaping through the holes in tire-chamber B, out ofwhich the ends of the cylinder protrude. The open space between itsupper edges will afford ample room for the action of the heatreverberated from the top a of the chamber of combustion, and thus theaction of the heat on the entire cylinder will be equalized.

Secured to the inside of the cylinder C is a double-inclined plane, M,set at right angles to the inside periphery, and on the edges of thedouble inclines are the lips m, which are bent at right angles totheplanes M, and these likewise at their inner edges, m', are bent so as tobe parallel with M, so that conveyingtroughs are thus made having anopenin g all along their length. There may be two ot' these inclinedplanes M on the inside of the cylinder. By means of these when thecylinder is rotated the contents, being by gravity greater on the lowerside thereof, lodge against said doubleinclined planes and are carriedup; but as they are carried upon said doubleinclined planes, the apexbeing in the middle lengthwise of said cylinder, they begin to slidedown said double-inclined planes, one-half to each end, and then lodgeagainst the lip m as the cylinder still revolves, and next slide towardthe middle of said cylinder on the lip between the doubleinclined planesand the lip on the lip of said inclined planes. Thus at each revolutioneach double-inclined plane with the lips throws the contents tothe endof said cylinder and then to the middle. There are also secured to theinside of said cylinder, and alternating with said double inclines M,the single inclines N, extending from end to end of the cylinder, havinga flange on their edges at right angles therewith, so that a section ofsaid inclines will be T-shaped. Thus on-each side of said inclines N areformed channels, down or along which the contents are carried from endto end of the cylinder at each revolution thereof. By this constructionis assured the most thorough and continuous stirring in all ways of eachgrain or nut ofthe contents. It is not enough that the grains or nutsshall be caused to slide and be pushed about as they are roasted,because even then', with the utmost care, they may sometimes be burned,but the several pieces must be picked up, turned over, and thrown in allways to insure even, thorough, and perfect roasting.

, The peanut warmer and exhibitor K, which is preferably of the shape ofa truncated pyramid, is permanently or detachably fixed in the upperpart of the structure or casing O, which is attached in any suitable wayto the side ofthe structure A. The roasted peanuts can be placed withinit through the doors k in its top, and the condition ot' the contentscan be observed through the glasscovered receptacle K in the fourinclined faces from its top. The contents may be kept warm by means ofwater in the chamber k2 in the bottom, which will be heated by thecirculation of hot air and the volatile products of combustion throughthe chamberL beneath it, or, when the damper i' is closed, by means ofalamp or suitable heating agent placed in the base O. When such a heateris placed centrally under the opening o', which is controlled by thedamper l, said damper being drawn out, the heater acts directly againstthe depending part 7c3 of the chamber k2 and eftectually raises thewater to the desired degree of heat. It will be noticed that the wateror steam chamber surrounds the base of the chamber K. To insure a flowof steam from the base into the upper part of k2, which comes about theinterior sides of the part K, pipes k4 may be used. The chamber 7cIl maybe filled with water by pipep, and this may also be used as an escapefor the steam. It may be supplied with a cut-od', and also'have awhistle to indicate the state of steam in the waterchamber k2.

IOO

Thus is oil'ered in a combined and very compact device the entireapparatus for roasting peanuts and for keeping them in readiness in thebest condition for use. The capacity ot' the roasting apparatus is soconsiderable that with a proper degree of heat and ordinary care a verygreat quantity of peanuts can be roast' ed, and with the very least percent-of damage-indeed with almost none.

The means provided for heating the warmer to a proper temperature aresuch that all this is done without any considerable cost and in theeasiest and most thorough manner.

Having thus described my invention, what I l IIO AIC)
